Earths oceans absorb carbon dioxide emitted by humans and other animals, and eventually turn it into carbonate rocks. which ''spheres'' are part of this process? select all that apply.
biosphere
exosphere
geosphere
cryosphere
atmosphere
hydrosphere

Option (1), (3), (5) and (6)

Explanation:

Carbon dioxide is a gas that is released by the living organism during respiration. This gas is then released into the atmosphere. This CO₂ gas is then carried to the lithosphere from the atmosphere with the help of rainfall. Now, these atmospheric CO₂ gas reacts with the water forming carbonic acid. Carbonic acid is a weak type of acid. This carbon is then squeezed and constricted to the sediments and muds, forming rocks such as shale and limestone.

Here, the carbon is present in the form of carbonate rocks.

Thus, this entire process takes place interacting with the biosphere, atmosphere, hydrosphere and geosphere.

Hence, the correct answer is option (1). (3), (5) and (6).

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
